Comparison
Verdict in brief
The FTG2000 and FTG2200 share the same large FTG class — 1,710 lb on the page (2,140 lb with water), a 1 1/2" NPT male gas connection, 3" grooved water connections and the same 235 MBH minimum fire. The 2200 adds 200 MBH of input ceiling and lifts heating capacity from 1,920 to 2,103 MBH and the Net AHRI rating from 1,670 to 1,829 MBH, while thermal efficiency eases from 96% to 95.6%.

Both boilers fire from the same 235 MBH minimum, so at low fire they behave identically; the FTG2200's 200 MBH of extra ceiling is pure headroom at the top of the range. NTI lists the 2000 at 235 to 2000 MBH input with 96% thermal efficiency, a 1,920 MBH heating capacity and a 1,670 MBH Net AHRI rating.
The 2200 runs 235 to 2200 MBH at 95.6% thermal efficiency with a 2,103 MBH heating capacity and a 1,829 MBH Net AHRI rating. Weight, connections and venting are unchanged: 1,710 lb on the page (2,140 lb with water per the I&O manual), 1 1/2 in NPT male gas, 3 in grooved water connections and 8 in air inlet and flue runs to 150 ft.
Both are heating-only commercial fire-tube boilers under the FTG I&O manual's 10% Canada altitude derate. With the same minimum fire and physical class, the choice is simply whether the plant-demand calculation needs more than 2,000 MBH — if it does not, the 2000 keeps the higher efficiency rating.
NTI Boilers
The NTI Trinity FTG2000 is the entry of the 2,000 MBH-class FTG fire-tube boilers: 235 to 2000 MBH input at 96% thermal efficiency, with a 1,920 MBH heating capacity and a 1,670 MBH Net AHRI rating on a 1 1/2" NPT male gas connection.
NTI Boilers
The NTI Trinity FTG2200 fires 235 to 2200 MBH at 95.6% thermal efficiency with a 2,103 MBH heating capacity and a 1,829 MBH Net AHRI rating — the mid step of NTI's 2,000 MBH-class FTG fire-tube boilers at 1,710 lb.
Input rises from 235–2000 to 235–2200 MBH, heating capacity from 1,920 to 2,103 MBH and the Net AHRI rating from 1,670 to 1,829 MBH; thermal efficiency eases from 96% to 95.6%. Weight, connections and venting are identical.
Yes — both fire down to 235 MBH per the NTI product page, so the 2200 adds ceiling without raising the low-fire floor.
When plant demand exceeds the FTG2000's 2,000 MBH ceiling. With identical low-fire behaviour and physical class, the only reasons to stop at the 2000 are the capacity you would not use and its 0.4-point efficiency edge.
A consultation includes a heat-loss review so the size is right the first time.
